CROSSCUT-SAWING MACHINE.

Specification of Letters Patent No. 30,904, dated December 1 1, 1860.

To all whom it may concern.:

Be it known that I, S. A. WORTHEN, of Morrisville, in the countyof'Lamoille and State of Vermont, have invented a new and usefulImprovement in Wood-Sawing Machines; and I do hereby declare that thefollowing is a full, clear, and exact description of the same, referencebeing had to the annexed drawing, forming part of this specication, inthe several figures of which similar characters of reference denote thesame part.

Figure 1 is a top view of the machine. Fig. 2 is a side view of same.Fig. 3 is a transverse section on line x This is a crosscut sawingmachine in which the log is automatically released at the termination ofthe cut; the details of construction and operation being as follows:

In the drawing F is the main frame and S the saw reciprocated byrotation of wheel W by pitman connection P upon horizontal guides G,which move vertically upon rods R of main frame. The saw being raised bylever a and rod b, when the log is being adjusted after the cut.

The log is held in rests B and grasped by stud c and arms d of lever L.Said lever being held to the required position by the pendant springratchet I), (Fig. 3).

Secured to the vertically moving saw frame is a depending arm I, andconstituting part of the spring ratchet is the upward bent arm H.

As the saw passes through the log the arm I acts upon the arm H ofspring ratchet, releases the lever L and permits weight WV connectedtherewith to draw up the long arm of said lever and release the log atthe termination of the cut for the succeeding feed. The saw is thendrawn up, the log fed, and secured by lever L which is securely held bythe spring ratchet D.

I claim- The spring ratchet D, arm I, lever L, weight IV', and arm H, incombination with the reciprocating' saw and frame arranged and operatingsubstantially as and for the purpose set forth.

In testimony whereof I have hereunto signed my name before twosubscribing witnesses.
